As far as the stalling and not restarting until cool, my buddy's RC390 had the same issue. I'll check with him to see what they did exactly, but I know it took them a bunch of trial and error to find the problem. Then, the mechanic was out on a test ride and it spit the cam chain. They installed a completely new crate engine at no charge. It had maybe 2000 mi on it when the problems started.

Another possibility is a blown head gasket.
Oh gawd, I reeeaally hope its not something blown....or broke(ish).

I made sure after todays flush and bleeding of the old coolant that there were no air pockets.

I look forward to hearing how your buddy got around that cooling problem with his RC390.


Thanks guys
